BOTTLE-SEALING MACHINE.

Application filed September 28,1923. Serial No. 665,260.

My invention relates to bottle sealing machines. The principal object ofthe invention is to provide in machines of that; kind improved means forshifting the caps orclosures for the bottle or container tooperativeposition in the machine. In machines of this character heretoforeconstructed the caps are moved to position in the, machines by a springpressed pusher which engages the caps with something of a blow, tendingto deform caps and prevent uniformly satisfactory sealing of. thecontainers, especially if the cap is made of relatively thin material.One object of my 1nvention is to obviate this defect.

Other objects of my invention will appear more fully in the followingdetailed de 'scription and appended claims. I

The accompanying drawings forming a part of this specificationillustrate one einbodiment of mechanism containing my invention.

In the drawings, 7

Fig. 1 is a front view of the mechanism.

Fig. 2 is a side view of a portion thereof.

Figs. 3 and 4 are sections taken on line 3-3 of Fig. 2 and showing theapparatus in different positions; and

Fig. 5 is a side view of the cap pusher.

Referring to the drawings, 1 the sealing head 1 is provided with asealing gate 2 which is fulcrumed for pivotal movement about. the axisof the vertical shaft 3' into open or closed position. The gate 2 issplined to the shaft 3 as shown at 4 so as to rotate with the shaft 3. Acoil sprmg 5 surrounding the shaft 3 and connected at opposite ends withsaid shaft and a relatively fixed part of the machine tends to rotatethe shaft 3 in the direction to effect 7 the closing of the gate 2against the head 1. -The machine comprises a relatively fixed housing 6provided with a cam slot 7 in which is engaged a roller 8 carried by acollar 9 secured to the shaft 3. As roller 8 rises and falls in theinclined portion of the cam slot 7 during the operation of the.

machine, the shaft 3 rotates to effect the opening or closing of thegate 2. The opening of the gate is effected by the cam action on theroller 8 of the coacting wall of the cam slot 7, which action causes theshaft 3 to be rotated against the torsion of spring 5. To seal. theclosure inlet, 10 when the .and out ofthe way of the chute.

fore the cap inlet 10 has been moved to reg:

ister with the closure chute 12, the gate 2 has, of course, been movedto open position When the retaining pawl 13 is elevated a closure entersthe inlet 10 and bears against the liquid supply plunger 14. The capremains in this position until the plunger 14 is elevated after thebottle has been filled after which the closure is thrust by a pushercarried-bythe gate to a position above the bottle and below the capsealing throat 15. The skirt of the cap is adapted, upon furtherdownward movement of the sealing head,

to be contracted by throat l5 about the rib V at the mouth of the bottleto seal the cap in place on the bottle. The apparatus described intheforegoing detailed description is not per se new in this invention, Fora more detailed description of the construction and operation of suchapparatus, attention is directed to United. States patent to CallesonReissue No. 14,657, dated June 10,1919.- i

The cap pusher herein disclosed so constructed and arranged that insteadof striking the cap with a blow it engages the same with but. littleimpact and further tends to avoid deformation thereof by movinglaterally thereof during its engagement therewith. Referring to thedrawings, the pusher is movable horizontally in an exten sion 16 in thegate or closure 2, its path of movement being at an angle to the capinlet 10. The pusher comprisesa forward cap engaging portion 17 anda'rear body portion 18 to which the cap engaging .portion 17 is pivotedfor movement about a vertical axis, as shown at 19. A spring 20 bearingagainst the end wall of the extension 16;.of the gate or closure 2 andagainst the body. 18 of the pusher tends to move or maintain the ypusherso that the cap engagingv ortion 17 isprojected beyond the gate. he bodypertain 1.8 of the pueher is formed to partly enclose the spring 2U.

111611 with thebody portion 18 thereof.

The outergor projecting end of the cap engaging portion of the pusher isprovided. with a projection 22 which is arranged to. register with guideshown as in the form of a groove 24 in the bottom wall of the cap inlet10 when the gate 2 is entirely closed, the groove 24 beingarranged so asto be under those conditions in alinement with the path or movement or"the projection 22; so that the pusher is adaptedlto force the capinwardly of the head to its position above the bottle or container whenthe liquid supply plunger 14 is elevated in the sealing head. (See Fig.4.)

In Fig. 3 I have shown in dotted lines the J position of the partsduringthe closing of the gate at the time the pusher first comes intoengagement with the sealing head. It will be seen that in this positionthe projection 22 is to one side of the groove 24. The

projection 22 is accordingly held by the ead from engagementwith the'cap; andduring the further closing of the gate 2, the sealing head byits engagement with the projection 22 holds the pusher out of engagementwith the cap and causes the pusher to be retracted into the housing 16on the gate 2.' When the gate is entirely closed the' projection 22,having moved laterally towards the groove 24 during the closing of thegate 2, registers with the said groove. The pusher at that time engagesthe cap, having moved gradually in its lateral movement with respect tothe groove 24 into engagement with the cap.

Referring to Figs. 3 and 4'it will be seen that as the cap is movedinwardly by the pusher, the cap engaging end of the pusher moveslaterally or horizontally with respect to the cap so thatinstead ofexerting all of itspressure'in a thrust directly upon one point of the.cap the pusher applies its pressure to the cap in a combined lateral andforward movement The result of the ahove coaction of the pusher with thecap is to move the latter into position above the bottle cap or sealwithout'tlieobjectionahie deformation of the cap.

s As the groove 24 is not equally distant.

at every point from the axis of the'shaft 3, it is necessary that theprojection 22 on the cap engaging portion 17 of the pusher be capable ofyielding laterally with respect to the gate 2 when the gate is-ope-ned.This lateral yielding is permitted by the pivotal mounting of theportion '17 of the pusher with respect'to'the body'of the pusher; sothat upon opening ofthe gate the portion 1? v of the pusher can yield;laterally to permit the projection 22 to pass freely along-and" outofthe groove 24. The portion 17 of the pusher.

' the desired lateral movement thereof ith out binding against thegate 2and without obstruct-ion from the portion" 18 I of the 7 It is to beunderstood that changes and modifications may be made in the deviceshown and described without departing rom the spirit of my inventionandlthe scope of the appended claims.
